Concept, ContainsTxCache, ConceptVertex, Comparable<Concept>

Direct Known Subclasses:

SchemaConceptImpl, ThingImpl

public abstract class ConceptImpl
extends Object
implements Concept, ConceptVertex, ContainsTxCache

The base concept implementation.

A concept which can represent anything in the graph which wraps a tinkerpop Vertex. This class forms the basis of assuring the graph follows the Grakn object model.
